The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Polotno targets developers and saas builders and leads with templates and ai-image-generation.
Harbor uses custom enterprise pricing, while Polotno starts at $20.99/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Harbor offers broader built-in capabilities (7 features vs 6), while Polotno takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Harbor has a slight overall edge — but if no account required to start matters most to you, Polotno may still be the right call.
